Title: Vacuum cleaner
Inventor: SENOO HIROYUKI
IPC: A47L9/28
Filed: 2006-04-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide a vacuum cleaner which suppresses a high-frequency sound, and has a good usability.  <P>SOLUTION: This vacuum cleaner includes a resonance silencer, a rotation frequency calculating means 215, an air rate calculating means 218, and a driving controlling means 214. In the vacuum cleaner, the resonance silencer is equipped with a plurality of recess portions which resonate with a plurality of frequencies being determined by an integral multiple of a product of the number of blades of a centrifugal fan of an electric blower 110 and the rotation frequency. The rotation frequency calculating means 215 calculates the rotation frequency of the electric blower 110. The air rate calculating means 218 calculates a suction air rate. The driving controlling means 214 controls the electric blower 110 in such a manner that the calculated rotation frequency may approach a specified target rotation frequency which is preset corresponding to the resonance frequency of the resonance silencer for each air rate section to which the calculated air capacity belongs. Thus, the vacuum cleaner is constituted to muffle a generated high-frequency sound by the plurality of frequencies. In this manner, even when a variation in air rate or the like occurs resulting from a refuse accumulation in a dust collecting chamber, the suction air rate can be determined. After determining the rotation frequency being suitable for the refuse accumulation, the rotation frequency of the electric blower is kept at the specified target rotation frequency, and the effect of the resonance silencer can always be demonstrated.  <P>COPYRIGHT: (C)2008,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To make a player more interested in games by executing the presentation matching the psychology of the player during the variation of symbols.  <P>SOLUTION: A specific ready-to-win mode is executed when the game state is a probability variable game state and ornament symbols as part of non-probability variable symbols are displayed in a ready-to-win mode; and in the ready-to-win presentation executed after that, such presentation is executed as to actively extract non-probability variable ready-to-win failure symbols. Accordingly, the presentation matching the psychology of the player, who does not want to make a non-probability variable jackpot while the game state is the probability variable state, can be executed during the variation of the ornament symbols. If a specific ready-to-win mode is executed when the game state is the probability variable state, and ornament symbols as part of the non-probability variable symbols are displayed in the ready-to-win mode, the player can feel that the probability of the non-probability variable ready-to-win failure symbols being extracted/displayed is high, and therefore, the player can be more interested in the games.  <P>COPYRIGHT: (C)2008,JPO&INPIT
